Among the lot, lemme today introduce you to Indian Indiana Jones.
He invested 50k and bought a portable metal detector. It had headphone and all that we see in movies.
His intentions was to provide the 'much needed service of finding hidden treasures in your land.
His hoped that before developing a piece of land, the owner will hire him to find old gold hidden in his plot.
When he got no clients in Bangalore, he shifted base to Chikbalapur and went about the countryside wearing a ridiculous hat looking for hidden treasure.
As far as i know he never found a nugget.
